    Another useful SMTP command to consider is EXPN, which will tell you what
    an alias expands to.  A while back someone submitted `expn.pl' to
    comp.sources.reviewed (which is archived many places including UUNET and
    many source CDROMs) which will take an email address and produce a list of
    all the destination mailboxes (addresses which don't explode or forward).
    Most of this code could be ported to MOO pretty easily.
